I've noticed that Black Crusade reassigned some of the characteristics linked to skills. The errata indicates that Willpower should be linked to Intimidate (but note that this is not carried over into Only War - pointed out because this is the newest and theoretically most playtested ruleset). However, there are others that stand out too:
The character sheet indicates that Operate (Voidship) should be Agility while Table 3-2 and the skill section says it should be Intelligence. Only War links this skill to Agility.
The character sheet and the skill section indicate that Inquiry should be Fellowship while Table 3-2 says it should be Intelligence. Only War links this skill to Fellowship.
My own feelings on these are leaning toward Table 3-2. This table already had Intimidate linked to Willpower, and I think I prefer that both Operate (Voidship) and Inquiry to br linked to Intelligence.
Is there any official answers on these skill/characteristic sets? Is there any known reason that Only War reverted Intimidate back to Strength?
For OW:s choice of chancing Intimidate (Willpower) to (Strength) is little obscure. Might be that it's easier to use your own bulk (Strength) to make people affraid of you.
Operate (Voidship) is understandaple mistake as Operate (Surface, Aeronautical) are Agility based and only place where in OW it says it's Intelligence based is p.129 upper left corner sidenote. And make note that they don't separate Operate Skill in the OW table 4-3 like in BC table 3-2
Inquiry Fellowship or Intelligence? For Fellowships defence it would be understandable that people like you and you know how to talk to them (like in OW:s choice of Fellowship & Social Aptitudes) but for Intelligence's defence you would need to know what questions to ask and where.
Must wait till they publish Errata to see what possible changes they are going to make for OW in Errata.
Actually, Intimidate has always (at least in DH) been on strength, and its like that in Black Crusade too. Its Opposed Strength vs Willpower. I take the actual skill description over any table or character sheet.
As for Operate: Voidships, I've always thought that Intelligence would be a better fit for it then Agility. Even the fastest Maneuvers take several minutes and need steady resolve, and a very good understanding of the vast physics involved in maneuvering a several kilometer hunk of metal out of a warp rift.
You could make an argument for either side though, and as a GM I would let a player pilot with the stat they want. After all a Tech Priest Captain or a Princeps probably don't pilot their vehicle through personal agility, but rather mentally sorting through massive piles of data and acting on the most logical one.
Inquiry, should be almost purely fellowship, unless you are dealing with tech priests.
If in doubt just go with the Skill Description, not the tables, until it gets cleared up.
